Dr. Allen was employed by Combustion Engineering - Superheater
Ltd. from 1975 - 76, where he was involved in the design, fabrication
and testing of control systems for oil, gas, and coal-fired steam
generators. Following completion of graduate studies at the University
of Western Ontario, Dr. Allen took a position with Pratt & Whitney
Aircraft as an aerodynamicist on a team working on the design of an
advanced turbo-prop gas turbine. After one year with Pratt & Whitney,
a leave of absence was granted in order to spend a year at the Budapest
Technical University in Hungary.

In 1980, Dr. Allen joined the Technical University of
Nova Scotia as a lecturer in Fluid Mechanics and Thermodynamics. In
1984, Dr. Allen was promoted to Assistant Professor. Since then Dr.
Allen has been instructing Thermodynamics, Heat Transfer, Energy from
Renewable Resources and Energy Conversion Systems.

Dr. Allen's research has been in two areas: (i) thermal
and hydraulic performance of heat exchangers for use in low-flow and/or
in buoyancy induced-flow applications and (ii) solar thermal energy
utilization, specifically the application of liquid flat-plate collectors
for heating. The research has been and is currently funded by the
Department of Natural Resources and NSERC. Dr. Allen's consulting
activities have also been in these same areas and he is active in
a private company, Thermo Dynamics Ltd., which is involved in the
research, development and manufacture of solar thermal equipment for
domestic and export markets.

Dr. Allen has been active in the solar energy research
and development community. He currently serves as the Chairperson
of the R & D Technical Advisory Committee of Natural Resources Canada,
a committee that advises the Federal Government on formulation of
policy on research and development in the area of renewable energy
utilization. Dr. Allen is a Member of the Board of the Solar Energy
Society of Canada (SESCI), and the Canadian Solar Industries Association.
Recently Dr. Allen completed a three year tenure of service with the
Canadian delegation to the International Energy Agency's task force
on advanced solar water heating. He also serves on the advisory committee
to the Centre for Sustainable Economic Development (CESED).
